He really should have refused the DNA swab. You can do that, you know. There's very little information you are obliged to give the police when you are arrested, although they will phrase their entreaties in such a way as to make it sound like you have no choice, and if you're a decent law-abiding type you're likely to be dazed and anxious to be a good citizen and do as they tell you. Polite refusal just means you might have an hour or two longer in the cell, but better that than ending up on the database for something you didn't do.
